2-3. Example of Flow of Display Control Process

An example of the flow of the display control process performed by theinformation processing system 1 will be described with reference toFIGS. 5 and 6.

(1) Pre-Process

FIG. 5 is a sequence diagram illustrating an example of the flow of thepre-process of the display control process according to the embodiment.Referring to FIG. 5, an example of the sequence of the pre-process whichinvolves the user, the portable terminal 20, the information processingdevice 100, and the display device 10 is shown.

First, the pre-process of the display control process starts when theuser designates content data to be reproduced (step S102). For example,the user selects a desired item from a list of content data displayed onthe display surface of the touch panel 110 of the information processingdevice 100 and touches the selected item, thereby designating contentdata.

Next, the data obtaining unit 140 of the information processing device100 obtains the designated content data from the storage unit 130 of theinformation processing device 100, the storage unit 26 of the portableterminal 20, or an external network (step S104). In addition, the dataobtaining unit 140 obtains UI formation data which is correlated withthe content data in step S104, and defines a correspondence relationshipbetween the user input and an operation of objects included in thecontent data (step S106).

FIG. 7 is a diagram illustrating an example of the UI formation datacorrelated with content data. FIG. 7 shows an example of the data formatof content data 132. In the data format in FIG. 7, the content data 132includes a common header 134, an expanded header 136, and object data138. The common header 134 stores standard header information such as,for example, the kind of content data, the creation date, and the datalength therein. The object data 138 stores actual data of objectsforming a content item therein.

The UI formation data is stored in, for example, the expanded header136. The UI formation data includes, for example, information on asensor to be used, and operation definition information. The informationon a sensor to be used is information specifying a sensor used foroperation of the objects included in the actual data in the object data138. The information on a sensor to be used may be a bit stream or or acode value indicating use or nonuse for each kind of sensor such as, forexample, a gyro sensor, an electronic compass, an acceleration sensor,and a touch panel. The operation definition information is informationwhich defines mapping between user inputs detected via theabove-described sensor and more abstract operation contents of anobject.

FIG. 8 is a diagram illustrating an example of the mapping between userinputs and operation contents. FIG. 8 shows the kinds of user inputs andcorresponding operation contents in relation to six input events Ev01,Ev11, Ev12, Ev13, Ev21, and Ev31 of the user inputs. For example, a tapon the touch panel of the information processing device 100 correspondsto a selection of an object to be operated (event Ev01). A drag on thetouch panel corresponds to one of a movement, a size change, and aviewpoint change of an object, according to three kinds of input states(events Ev11 to Ev13). A change in the orientation detected by thesensor of the portable terminal 20 corresponds to rotation (3D rotationor 2D rotation) of an object (event Ev21). A movement direction of anobject corresponding to the input event Ev11 may be changed when theorientation of the object is changed through the rotation of the object.For example, a UI may be realized in such a manner that if an objectstands upright, the object travels in a straight line according to theinput event Ev11, and if the object is tilted, the object is moved in acurved manner according to the input event Ev11. The pressing of apredetermined button of the portable terminal 20 corresponds toswitching between input states (event Ev31).

The definition of the mapping between the user inputs and the operationcontents in FIG. 8 is only an example. For example, among the drags onthe touch panel, a drag in the vertical direction may be mapped onto asize change of an object, a drag in the horizontal direction may bemapped onto a movement of an object. In addition, mapping between theuser inputs and the operation contents may be customized or personalizedfor each user. However, when the UI functions for operating objects aredistributed into the portable terminal 20 and the touch panel 110 of theinformation processing device 100, a change in the orientation of anobject, that is, rotation of the object is preferably mapped onto achange in the orientation of the portable terminal 20. This is becausethe portable terminal 20 can be flexibly changed in the orientation in astate of being held by the user, whereas the touch panel 110 of theinformation processing device 100 is disposed on the table 50 so as tobe substantially fixed. If a control of the orientation of an object inthe portable terminal 20 and a control of a movement of the object inthe touch panel 110 are performed at the same time, the user canflexibly operate the object with both the hands.

In addition, an example where the UI formation data is included in theheader of the content data has been described here. However, forexample, in a case where a UI configuration is standardized for aspecific content item, the UI formation data may be omitted from thecontent data. In addition, only a URL (Uniform Resource Locator)indicating the position of the UI formation data is described in thecontent data, and the information processing device 100 may access theURL and additionally obtain the UI formation data.

Referring to FIG. 5 again, the description of an example of thepre-process of the display control process is continued.

If the content data designated by the user is obtained, the control unit160 of the information processing device 100 outputs a content image inan initial state via the display output unit 150 and displays thecontent image on the display device 10 (step S108).

If the UI formation data correlated with the content data, the controlunit 160 searches for devices having the sensor designated by theinformation on a sensor to be used inside the UI formation data (stepS112). For example, the communication unit 120 transmits a query packethaving a predetermined format to peripheral devices of the informationprocessing device 100, thereby performing the device search. If thequery packet is received from the information processing device 100, theportable terminal 20 responds to the device search by transmitting aresponse packet to the query packet (step S114).

FIG. 9 is a diagram illustrating an example of the packet format of thequery packet for the device search. Referring to FIG. 9, an exemplaryquery packet 132 includes a query header 134, query side functioninformation 136, and request function information 138. The query header134 stores header information such as, for example, ID of the querypacket, ID of the information processing device 100, the kind of packetformat, and the packet length therein. The query side functioninformation 136 includes information on the capabilities (for example,the kind of available communication protocol, the kind of sensor, andthe like) of the information processing device 100 which is the queryside. The request function information 138 includes information onfunctions requested for a device receiving the query. In the exampleshown in FIG. 9, a list of sensors requested to realize a desired UI isincluded in the request function information 138.

FIG. 10 is a diagram illustrating an example of the packet format of theresponse packet to the query packet shown in FIG. 9. In FIG. 10, anexemplary response packet 142 includes a response header 144, andresponse side function information 146. The response header 144 storesheader information such as, for example, ID of the response packet, IDof the corresponding query packet, ID of the portable terminal 20, andthe packet length therein. The response side function information 146includes information on the capabilities of the portable terminal 20which is a response side. In the example shown in FIG. 10, the responseside function information 146 includes a list of sensors available tothe portable terminal 20 of the sensor group indicated by the requestfunction information 138 of the query packet.

Referring to FIG. 5 again, the description of an example of thepre-process of the display control process is continued.

If the response packet is received from the portable terminal 20, thecontrol unit 160 of the information processing device 100 establishescommunication with the portable terminal 20 through, for example,exchange of connection information, mutual authentication, and the like(step S116).

Next, the control unit 160 displays operation guidance on the displayunit 114 based on the operation definition information included in theUI formation data (step S118). FIG. 11 is a diagram illustrating anexample of the operation guidance displayed by the display unit 114. InFIG. 11, exemplary operation guidance 150 includes a touch region range152, an input state display portion 154, and a terminal operationexplanation portion 156. The touch region range 152 is a frameindicating a region where a user performs a user input, such as a touchor a drag. The input state display portion 154 indicates a current inputstate among a plurality of input states and a switching method of theinput state. The terminal operation explanation portion 156 indicates anexplanation for what kind of operation is performed using the portableterminal 20. In addition, in a case where there is a sensor which is notavailable to the portable terminal 20, an explanation for the sensor maybe shown in the terminal operation explanation portion 156. The userconfirms the operation guidance and uses both the portable terminal 20and the touch panel 110 of the information processing device 100,thereby operating operable objects displayed by the display device 10.

When the operation guidance as exemplified in FIG. 11 is displayed, thepre-process of the display control process in the information processingsystem 1 is completed.

(2) Display Control Process

FIG. 6 is a sequence diagram illustrating an example of the flow of thedisplay control process according to the embodiment. The display controlprocess subsequent to the pre-process involves the user, the portableterminal 20, the information processing device 100, and the displaydevice 10. In addition, the display control process is typicallyperformed by an event driving method. Therefore, the procedures and thenumber of the user inputs shown in FIG. 6 are merely for convenience ofdescription. In the following description, a user input detected by thetouch panel 110 of the information processing device 100 is referred toas a first user input, and a user input detected by the portableterminal 20 and received by the communication unit 120 of theinformation processing device 100 is referred to as a second user input.

For example, if the first user input is detected by the touch panel 110(step S130), the control unit 160 executes a first operation of anobject displayed in the content image (step S132). As described withreference to FIG. 8, for example, the first user input may be a touch bythe user on the touch panel 110, and the first operation may be aselection of an operation target object from a plurality of operableobjects. Further, for example, the first user input may be a drag by theuser on the touch panel 110, and the first operation may be a sizechange, a movement, or a viewpoint change of an object. The control unit160 analyzes the first user input based on an input state, and outputs acontent image according to the first operation (step S134).

In addition, for example, if the second user input is detected by theportable terminal 20 (steps S140 and S142), the control unit 160executes a second operation of an object displayed in the content image(step S144). As described with reference to FIG. 8, for example, thesecond user input may be a change in the orientation of the portableterminal 20, and the second operation may be a change in the orientationof an object. The control unit 160 recognizes the second user inputbased on the sensor data received by the communication unit 120, andoutputs a content image according to the second operation (step S146).

For example, if the first user input is detected by the touch panel 110(step S150) and the second user input is detected by the portableterminal 20 (steps S152 and S154), an operation of an object differentfrom the first and second operations may be executed (step S156). Forexample, the object may be moved based on the first user input in adifferent direction according to the orientation of the object which hasbeen changed because the orientation of the object is changed based onthe second user input. The control unit 160 may output a content imagecorresponding to such an operation (step S158).

FIG. 12 is a diagram illustrating an example of the packet format of thesensor data packet which may be transmitted to the informationprocessing device 100 from the portable terminal 20 in steps S142 andS154 shown in FIG. 6. In FIG. 12, an exemplary sensor data packet 152includes a sensor data header 154, and one or more sensor data fields156 a to 156 n. The sensor data header 154 may include, for example, IDof the portable terminal 20, the number of sensor data fields in thepacket, a time stamp indicating measurement time, and the like. Each ofthe sensor data fields 156 a to 156 n may include a measurement resultaccording to the kind of sensor. For example, the sensor data mayinclude an angular velocity for each rotation direction in relation tothe gyro sensor, an azimuth in relation to the electronic compass, atriaxial acceleration in relation to the acceleration sensor, and a datavalue of a touched position, a dragged position, or the like in relationto the touch panel.

2-4. Process in Each Device (1) Master Side Device

FIG. 13 is a flowchart illustrating an example of the flow of theprocesses performed by the information processing device 100 working asa master of the UI according to the embodiment.

In FIG. 13, first, the data obtaining unit 140 obtains content data(step S161). Next, the data obtaining unit 140 obtains UI formation datacorrelated with the content data (step S162). The control unit 160recognizes a sensor, which is used in a UI for an operation of objectsincluded in the content data, from the UI formation data (step S163). Inaddition, the control unit 160 outputs a content image in an initialstate to the display device 10 via the display output unit 150 (stepS164).

Thereafter, the communication unit 120 transmits a query packet fordevice search (step S165). The information processing device 100 waitsfor responses from peripheral devices (step S166). Here, if there is noresponse even after a predetermined waiting time has elapsed, thecontrol unit 160 controls an operation of an object without using otherdevices (step S167). On the other hand, for example, if a responsepacket is received from the portable terminal 20, the control unit 160establishes communication with the portable terminal (step S168). Inaddition, the control unit 160 displays the operation guidance asexemplified in FIG. 11 on the display unit 114 according to the UIformation data (step S169).

Thereafter, the control unit 160 waits for a user input to be detected(step S170). If the user input is detected, the control unit 160recognizes an input event from the user input, and controls an operationof an object according to the recognized input event. In addition, thecontrol unit 160 updates a content image output to the display device 10(step S171). Such an operation of an object may be continued until, forexample, reception of sensor data from the portable terminal 20 stops(step S172). In addition, if the sensor data stops being received, thecontrol unit 160 finishes the communication with the portable terminal20 (step S173). Further, the communication between the portable terminal20 and the information processing device 100 may be finished due to anexplicit instruction from a user or other events, and not the stop ofsensor data reception.

(2) Slave Side Device

FIG. 14 is a flowchart illustrating an example of the flow of theprocesses performed by the portable terminal 20 working as a slave ofthe UI according to the embodiment

First, the communication unit 24 of the portable terminal 20 waits forthe query packet for device search to be received from the informationprocessing device 100 (step S181). If the query packet is received bythe communication unit 24, the control unit 30 generates a responsepacket including a list of sensors available to the portable terminaland generates the response packet to the information processing device100 via the communication unit 24 (step S182). In addition, the controlunit 30 establishes communication with the information processing device100 (step S183).

Thereafter, the control unit 30 continues to transmit data measured bythe sensor of the input unit 22 to the information processing device 100via the communication unit 24 as sensor data (step S184). In addition,the control unit 30 may transmit an input event such as pressing of apredetermined button to the information processing device 100. Thecommunication between the portable terminal 20 and the informationprocessing device 100 may be continued, for example, until aninstruction for finishing an operation of an object is detected, oruntil it is detected that a user becomes distant from the informationprocessing device 100 (or the table 50) (step S185). In addition, thecontrol unit 30 finishes the communication with the informationprocessing device 100 along with the finishing of an operation of anobject (step S186).

3. Description of Second Embodiment

Next, according to a second embodiment of the present disclosure, anexample of the flow of the processes when the portable terminal 20 worksas a master of the UI and the information processing device 100 works asa slave of the UI will be described.

(1) Pre-Process

FIG. 15 is a sequence diagram illustrating an example of the flow of thepre-process of the display control process according to the secondembodiment. Referring to FIG. 15, an example of the sequence of thepre-process which involves the user, the portable terminal 20, theinformation processing device 100, and the display device 10 is shown.

First, the pre-process of the display control process starts when theuser designates content data to be reproduced (step S202). For example,the user selects a desired item from a list of content data displayed onthe display unit 32 of the portable terminal 20, thereby designatingcontent data.

Next, the data obtaining unit 28 of the portable terminal 20 obtains thedesignated content data from the storage unit 26 of the portableterminal 20, the storage unit 130 of the information processing device100, or an external network (step S204). In addition, the data obtainingunit 28 obtains UI formation data which is correlated with the contentdata in step S204 and defines a correspondence relationship between theuser input and an operation of objects included in the content data(step S206), and if the content data designated by the user is obtained,the control unit 30 of the portable terminal 20 outputs a content imagein an initial state via the display output unit 34 and displays thecontent image on the display device 10 (step S208).

If the UI formation data correlated with the content data, the controlunit 30 searches for devices having the sensor designated by theinformation on a sensor to be used inside the UI formation data (stepS212). For example, the communication unit 24 transmits a query packethaving a predetermined format to peripheral devices of the portableterminal 20, thereby performing the device search. If the query packetis received from the portable terminal 20, the information processingdevice 100 responds to the device search by transmitting a responsepacket to the query packet (step S214).

If the response packet is received from the information processingdevice 100, the control unit 30 of the portable terminal 20 establishescommunication with the information processing device 100 through, forexample, exchange of connection information, mutual authentication, andthe like (step S216).

Next, the control unit 30 transmits the operation definition informationincluded in the UI formation data to the information processing device100 and displays operation guidance on the display unit 114 of theinformation processing device 100 (step S218). When the operationguidance as exemplified in FIG. 11 is displayed, the pre-process of thedisplay control process according to the embodiment is completed.

(2) Display Control Process

FIG. 16 is a sequence diagram illustrating an example of the flow of thedisplay control process according to the embodiment. The display controlprocess subsequent to the pre-process involves the user, the portableterminal 20, the information processing device 100, and the displaydevice 10. In addition, the procedures and the number of the user inputsshown in FIG. 16 are merely for convenience of description.

For example, if the first user input is detected by the touch panel 110of the information processing device 100 (step S230), the control unit30 of the portable terminal 20 receives sensor data indicating a touchedposition from the information processing device 100 via thecommunication unit (step S232). In addition, the control unit 30executes a first operation of an objected displayed in the content image(step S234), and outputs a content image according to the firstoperation (step S236).

In addition, for example, if the second user input is detected by thesensor of the input unit 22 (step S240), the control unit 30 executes asecond operation of an object displayed in the content image (stepS242). The control unit 30 outputs a content image according to thesecond operation (step S244).

For example, if the first user input is detected by the touch panel 110(steps S250 and S252) and the second user input is detected by thesensor of the input unit 22 (step S254), the control unit 30 may executean operation of an object different from the first and second operations(step S256). The control unit 30 outputs a content image according tothe operation of an object, different from the first and secondoperations (step S258).

The operation of an object executed in the display control process maybe the same as the operation according to the mapping between userinputs and operation contents as exemplified in FIG. 8.

4. Conclusion

The first and second embodiments of the present disclosure have beendescribed hitherto with reference to FIGS. 1 to 16. According to theembodiments, there is a realization of the user interface which usesboth the first user input detected by the touch panel 110 of theinformation processing device 100 and the second user input detected bythe portable terminal 20. That is to say, since variations of userinputs are expanded as compared with a case of performing an operationwith a single device, a user can flexibly move objects using twodevices. Particularly, in recent years, various sensors have beenminiaturized, and the miniaturized sensors have been mounted on avariety of portable terminals represented by smart phones. Therefore,according to the embodiments described above, it is possible toeffectively improve the convenience of operations by expanding a userinterface of a cradle type computer (or a computer placed on a table atleast during use thereof) using sensors of portable terminalsdistributed in the market. In addition, a device (for example, a touchpanel terminal such as the information processing device 100, or a TVset such as the display device 10) which does not have an appropriateinput portion for inputting characters such as a key pad is linked to aportable terminal, and thereby it is possible to resolve inconveniencewhen characters are input to the device.

In addition, a user can move while handling the touch panel of theinformation processing system with the right hand and grasping theportable terminal with the left hand. Therefore, the user can perform anintuitive or smooth operation by appropriately distributing the UIfunction into the two devices.

For example, the second user input corresponds to a change in theorientation of the portable terminal, and the second operationcorresponds to a change in the orientation of an object in a contentimage. Therefore, it is possible to operate the orientation of theobject using the portable terminal which can freely change itsorientation regardless of the installation surface. Such a userinterface is useful for a case where, particularly, an operation targetis displayed in 3D space.

In addition, for example, the first user input is a drag by a user onthe touch panel of the information processing device, and the firstoperation is a size change, a movement, or a viewpoint change of anobject in a content image. Generally, a drag on a touch panelfacilitates reflecting the distance and the direction desired by a usermore accurately than a case of moving a portable terminal in an actualspace. Therefore, in a case where accuracy of an operation is expectedto an extent, employing the above-described configuration is favorablerather than mapping both the movement and the orientation change of anobject onto user inputs to a portable terminal.

In addition, according to the above-described embodiments, a contentimage is output to an external display device, and operation guidanceregarding an operation of an object is displayed on the touch panel ofthe information processing device. Thereby, a user can easily operate anobject in the content image while viewing the operation guidance.

In addition, a series of processes performed by the portable terminaland the information processing device, described in the presentspecification, may be realized using any of software, hardware, or acombination of software and hardware. A program constituting thesoftware is stored in, for example, a storage medium installed inside oroutside each device in advance. In addition, each program is loaded to,for example, a RAM (Random Access Memory) during execution, and isexecuted by a processor such as a CPU.
